No, rice chex are not primal. And yes, it looks like another sugar war. All the usual suspects have arrived.
To the OP: Rice Chex are not primal. Please go read the books, or at least read the information on this site, to find out what's primal. If you need something "quick" for breakfast, you'll have to make it the night before. My breakfast is a smoothie with berries and whey powder and two hard-boiled eggs. Both are transportable. But you're 16, you better be eating huge lunches and dinners with lots of high-quality meat, a little bit of butter, and a few veggies for variety and antioxidants.
5'0" female, 44 years old. Started Primal October 31, 2011, at a skinny fat 111.5 lbs. Low weight: 99.5 lb on a fast. Gained back to 115(!) on SAD chocolate, potato chips, and stress. Currently keeping food tracker.
I (try to) follow by-the-book primal as advocated by Mark Sisson, except for whey powder and a bit of cream. I advocate a two-month strict adjustment for newbies. But everybody is different and should tweak Primal to their own needs.
